Response Structure

- ClusterListEntries (list) –
  
  Each ClusterListEntry object contains a cluster’s state, a cluster’s ID, and other important status information.

    Contains a cluster’s state, a cluster’s ID, and other important information.
    - ClusterId (string) –
      
      The 39-character ID for the cluster that you want to list, for example CID123e4567-e89b-12d3-a456-426655440000 .
    - ClusterState (string) –
      
      The current state of this cluster. For information about the state of a specific node, see JobListEntry$JobState.
    - CreationDate (datetime) –
      
      The creation date for this cluster.
    - Description (string) –
      
      Defines an optional description of the cluster, for example Environmental Data Cluster-01 .
- NextToken (string) –
